Última BENEFITS TRANSFER AND COUNT DATA TRAVEL COST MODELS: AN APPLICATION AND TEST OF A VARYING PARAMETER APPROACH WITH GUIDED WHITEWATER RAFTING AgEcon Bowker, James Michael; English, Donald B.K.; Bergstrom, John C.. We combine currently popular count data methods with earlier work by Vaughan and Russell on varying parameter travel cost models to model trip demand and calculate consumer surplus. We test and reject the hypothesis that per trip consumer surplus from guided rafting is invariant to river characteristics. We then develop and test a series of benefit transfer functions against benefits derived from individual river models. Our findings suggest that this flexible form of count data model offers considerable promise as a benefit transfer function.

Ano: 1997 URL: http://purl.umn.edu/16703 Impact of Income on Price and Income Responses in the Differential Demand System AgEcon Brown, Mark G.. An extension of the Rotterdam model is developed that makes the model’s income flexibility and marginal propensities to consume varying coefficients. Frisch’s duality relationships that the second partial derivatives of demand with respect to income and prices are independent of the order of differentiation are imposed with the marginal propensities to consume specified as functions of income and price, and the Slutsky coefficients specified as functions of income only. A uniform substitute specification is used to analyze the conditional demands for a group of beverages.
